+# glee
+
+This command-line utility lets you manipulate .git repository's `info/exclude` file, which works like `.gitignore` but is completely local and not included in the repository itself.
+
+[Learn more about .git/info/exclude](https://git-scm.com/docs/gitignore)
+
+## Usage
+
+    # Add files to exclude list
+    glee add filename1 filename2
+
+    # Add multiple files to exclude list using glob pattern
+    glee add filename*.txt
+
+    # Add glob pattern itself to exclude list
+    glee add filename\*.txt
+
+    # Display entries in the exclude list
+    glee list
+
+    # Clear the exclude list
+    glee clear
+
+    # Display help
+    glee help
